The development of the stormwater management strategies, e.g., low-impact (LID), water-sensitive urban design (WSUD), and sustainable drainage solutions (SUDS), was initiated in mid-1980s as a set engineering approaches technologies to reduce harmful effects stormwater. Over time, all them evolved holistic, multidisciplinary and, today, they are increasingly viewed implemented under umbrella term “Nature-based Solutions” (NbS). technical elements measures these NbS represent various...

Optimizing the use of resources plays a significant role in concept development and functioning smart cities. This especially applies to rational consumption energy water use. At same time, application information technologies, databases, optimization models other techniques technologies becomes indispensable for implementation management strategy preparation decision-making that area. In addition, introduction sensors automated systems makes it possible obtain necessary data, respond timely...

<p>Regional analysis is often used for flood quantile estimation in ungauged catchments. The regionalization procedure has two phases: the formation of homogeneous regions and estimation. presented research results consider first phase regional 41 catchments Serbia. catchment similarity attributes are area mean elevation. number formed stations within determined by maximising silhouette width region. Regions were obtained cluster then adjusted to comprise with a positive width....

In the absence of detailed exploration karstic catchments, calculation available reserves and elements water balance equation frequently reflect topographic size catchment area, not actual, active (underground) size. The two differ largely where karst is concerned. paper deals with problem average area estimation in situation when meteorological data are limited to precipitation temperature, but discharge records for long period. Proposed methodology was applied to, calibrated, validated on...

Active water loss management has become one of the primary interests utilities in world. Due to efforts IWA Task Force last decade, traditional approach expression percentage system input values been proven be misleading may cases, and new way performance measuring benchmarking is proposed. This paper presents basic principles this methodology results first step attempt Serbian according standards. Pirot supply used as a case study estimate pressure reducing impact on technical indictor...

Flood quantile estimation in ungauged basins is often performed using regional analysis. A regionalization procedure consists of two phases: the definition homogeneous regions among gauged basins, i.e., clusters stations, and information transfer to sites. Due its simplicity widespread use, a combination hierarchical clustering by Ward’s algorithm index-flood method applied this research. While very efficient, shortcomings are lack flexibility clusters/regions inability objects/stations from...

Changes in the hydrological regime are widely investigated using a variety of approaches. In this study, we assess changes annual and seasonal flow characteristics based on probabilistic representation runoff at daily time scale. The pattern is constructed by determining quantiles from marginal distributions flows for each day within year. By applying Fourier transformation statistics partial series, obtain smooth periodical functions distribution parameters over year consequently quantiles....

Revision of existing methodologies for generating monthly-flow series at ungauged basins based on multivariate nonlinear correlation has led to a simple two-parameter model. While the methodology used hydrological, meteorological and geomorphologic input data, proposed model requires hydrological data only. The formation separate pools donor catchments parameter estimates. improvement in sphere homogeneous region identification were verified using 195 runoff sets from hydrologic stations...

The application of the ecologically oriented concept blue-green infrastructure in urban areas has numerous benefits at different spatial and functional levels city, roof one being improvement public health. However, this aspect carries risks with it. As risks, as well itself, have not been sufficiently studied Serbia, nor seen through planning engineering practice, paper aim is to review systematize modalities possibilities applying by reviewing reference literature analyzing selected...

In addition to climate change, factors affecting the future water regime at basin level also include changes in land use and cover. This study aims evaluate performance of three methods for predicting cover within Toplica River basin, up Doljevac hydrological station, until year 2100. Predictions were made using MOLUSCE plugin QGIS v2.18 software package. Four variants input data analyzed, combining digital elevation model indicators such as road distance, exposure, terrain slope. The kappa...

An analysis of mean annual runoff was conducted for a small ungauged catchment the Tulovska River in South Morava Basin. Langbein?s method, Turk?s method and regional regression models were applied obtaining runoff. Long-term temperature, precipitation elevation are used as input data. The estimations using various sources climatological data results then compared. Precipitation temperature derived, 10 km x resolution raster format, from digital repository CarpatClim project. Point...

The methods for performance measuring and benchmarking proposed by IWA Water Loss Task Force has been adopted worldwide during the last two decades.This methodology active water loss management is still poorly applied in Serbian supply systems.This research presents application of hydraulic modelling to estimate network town Pirot Eastern Serbia evaluate potential effects leakage saving using best practice.In model, diurnal demand multipliers total registered consumption exponent are...

Eighteen low flow indicators are considered in the research of sixteen hydrological stations Juzna Morava river basin. The estimated by statistical analysis and grouped as environmental indicators. A crosscorrelation between all is assessed. Environmental flows at hydrologic obtained GEP method. transferred to two small ungauged basins regression with physiographic characteristics. adjustment performed according locations donor hydrogeological regions studied area.

The aim of the presented research is improvement methodology for probability calculation coinciding occurrence historic floods and droughts in same year. original procedure was developed order to determine such an extreme event. There are two phases assessment both drought flood In first phase outliers detected as indicators events, their return periods calculated series' statistics adjusted. second conditional probabilities calculated: empirical points plotted, year assessed based on plot....

Abstract An initial step in flood hazard mapping is hydrological modelling. We present a recent river modelling approach Bosnia and Herzegovina (BiH) for small ungauged catchments of drainage area up to 32 km 2 . To estimate peak flow required probability catchments, we use the rational method. The paper focus GIS based procedure producing runoff coefficient map BiH from DTM land cover map. For validation results diagrams per catchment (specific runoff) versus medium large gauged catchments....

Vlasina Lake in south-east Serbia is classified as an Area of Distinct Land Use and, such, subject to high environmental protection standards applied the Master Plan. Two open channels for stormwater and sediment transportation two large detention basins with pumping stations water evacuation into lake were envisaged In preliminary design, system was quite different: wherever possible, on-site natural features used allocation ponds, drainage led through existing road culverts. The design...
