The present study has been carried out in the Tabriz River basin (5397 km2) north-western Iran. Elevations vary from 1274 to 3678 m above sea level, and slope angles range 0 150.9 %. average annual minimum maximum temperatures are 2 °C 12 °C, respectively. rainfall ranges 243 641 mm, northern southern parts of receive highest amounts. In this study, we mapped groundwater potential (GWP) with a new hybrid model combining random subspace (RS) multilayer perception (MLP), naïve Bayes tree...
Check dams are widely used watershed management measures for reducing flood peak discharge and sediment transport, increasing lag time groundwater recharge throughout the world. However, identifying best suitable sites check within stream networks of various watersheds remains challenging. This study aimed to develop an open-source software with user-friendly interface screening network possibilities guiding selection watersheds. In this developed site (SSS), multi-criteria decision analysis...
The extreme form of land degradation caused by the formation gullies is a major challenge for sustainability resources. This problem more vulnerable in arid and semi-arid environment associated damage to agriculture allied economic activities. Appropriate modeling such erosion therefore needed with optimum accuracy estimating regions taking appropriate initiatives. Golestan Dam has faced an acute gully over last decade adversely affected society. Here, artificial neural network (ANN),...
Floods are the most common natural disaster globally and lead to severe damage, especially in urban environments. This study evaluated efficiency of a self-organizing map neural network (SOMN) algorithm for flood hazard mapping case Amol city, Iran. First, inventory database was prepared using field survey data covering 118 flooded points. A 70:30 ratio applied training validation purposes. Six factors (elevation, slope percent, distance from river, channel, curve number, precipitation) were...
Gully erosion has become one of the major environmental issues, due to severity its impact in many parts world. directly and indirectly affects agriculture infrastructural development. The Golestan Dam basin, where soil degradation are very severe problems, was selected as study area. This research maps gully susceptibility (GES) by integrating four models: maximum entropy (MaxEnt), artificial neural network (ANN), support vector machine (SVM), general linear model (GLM). Of 1042 locations,...
The optimal prediction of land subsidence (LS) is very much difficult because limitations in proper monitoring techniques, field-base surveys and knowledge related to functioning behavior LS. Thus, due the lack LS susceptibility maps it almost impossible identify prone areas as a result influences severe economic human losses. Hence, preparation mapping (LSSM) can help prevent natural catastrophes reduce damages significantly. Machine learning (ML) techniques are becoming increasingly...
The present work sets out to 1) evaluate the corrosion-scaling potential of groundwater resources for industrial sector as well 2) examine chemical parameters agricultural in Piranshahr Watershed West Azerbaijan province, Iran, using geostatistical analyses and Wilcox diagram a GIS environment. A total 145 spring locations representatives potentiality were recorded by handheld GPS device corrosion scaling states further scrutinized. latter was carried on basis examining at each sample...
AbstractLand-subsidence (LS) is a common geo-hazard in many regions of the world. The overexploitation subsurface and ground water, followed by collapse underground cavities, one mechanisms that cause LS. Optimal prediction LS difficult due to limitations monitoring, surveying information about mechanism process Therefore, susceptibility mapping (LSSM) crucial prevent reduce economic damage natural manmade catastrophes. This study Isfahan Province, Iran, aimed map using hybrid model adaptive...
Abstract Gully erosion causes high soil rates and is an environmental concern posing major risk to the sustainability of cultivated areas world. Gullies modify land, shape new landforms damage agricultural fields. mapping essential understand mechanism, development, evolution gullies. In this work, a modeling approach was employed for gully susceptibility (GESM) in Golestan Dam basin Iran. The measurements 14 gully-erosion (GE) factors at 1042 GE locations were compiled spatial database....
