Understanding of water resources and trends consumptions is important to offer sustainable management strategy. In this research, in Saudi Arabia were investigated. The non-renewable groundwater reserves estimated be 259.1–760.6 billion cubic meters (BCM) with an effective annual recharge 886 million (MCM). total internal renewable was 2.4 BCM/year. Approximately 1.4 BCM/year runoff collected by 302 dams. country produces approximately 1.06 BCM desalinated annually. wastewater treatment...

This study investigated possible implications of climate change on crop water requirements (CWRs) from 2011 to 2050 in Al-Jouf, Saudi Arabia. CWR were predicted for four scenarios: (i) current temperature and rainfall (S1); (ii) state (S2); (iii) (S3) (iv) (S4). Assuming no the regulations relating agriculture irrigation future, be 873 931 million cubic meters (MCM) per year S1 S4 scenarios, respectively, indicating an increase 58 MCM 2050. On average, 1 °C may overall by 2.9% this region....

The aim of this study is to build a flood simulation model for the city Hafr Al-Batin catchment area. consists hydrologic model, hydraulic and pre- post-processing tools. A geographic information system-based modelling interface was used pre-process terrain rainfall data generate input files models. Soil map data, land cover map, use digital elevation delineate physical watershed's characteristics. runoff estimation based on widely known Conservation Service curve number approach....

A physically-based, distributed-parameter hydrologic model was used to simulate a recent flood event in the city of Hafr Al Batin, Saudi Arabia gain better understanding runoff generation and spatial distribution flooding. The is located very arid catchment. Flooding influenced by presence three major tributaries that join main channel around heavily urbanized area. Integrated Multi-satellite Retrievals for Global Precipitation Measurement Mission (IMERG) rainfall product due lack detailed...

Population growth and land use modification in urban areas require the of accurate tools for rainfall-runoff modeling, especially where topography is complex. The recent improvement quality resolution remotely sensed precipitation satisfies a major need such tools. A physically-based, fully distributed hydrologic model conceptual semi-distributed model, forced by satellite rainfall estimates, were used to simulate flooding events very arid, rapidly urbanizing watershed Saudi Arabia. Observed...

Water quality could vary within the water distribution system due to internal or external contamination. Thus, it is very important examine at selected locations of network ensure safe will be delivered end users. in needs sampled locations, which are representative whole network. These monitoring stations should located such that represented with a minimum number economical reasons. Presently, no guideline describes how these sampling optimally identified. In this paper, new methodology...

Rainfall is the most important input parameter for water resource planning and hydrological studies because flood risk assessment, rainfall harvesting runoff estimation depend on distribution within a region. Due to practical economic factors, it not possible site stations everywhere, so representative are sited at specific locations. then estimated from such stations. In this study, in southwestern region of Saudi Arabia was using kriging, co-kriging inverse distance weighted (IDW) methods....

The purpose of this study is to understand flooding in a 1,725-km2 arid catchment Makkah Province, Saudi Arabia, with very limited ground observations. This mountainous includes densely urbanized areas built on lowlands and the ephemeral streams flood zones, which makes them vulnerable flooding. A physically based, fully distributed hydrologic model was produced by three Integrated Multi-satellite Retrievals for Global Precipitation Measurement Mission (IMERG) high-resolution satellite...

Engineering predictions of flows in open-channel systems are fraught with ambiguity due to spatial and temporal variability, measurement error limited sampling the parameters that represent system properties, boundary initial conditions, sinks/sources. Over recent years, steady progress has been made addressing this uncertainty notions risk, reliability, confidence poses planning, design, management decisions. A number simplified approaches have explored for modeling flow as a stochastic...

Abstract This study examines precipitation accumulation and intensity trends across a region in southwest S audi A rabia characterized by distinct seasonal weather patterns mountainous terrain. The is an example of arid/semiarid area faced with maintaining sustainable water resources growing population. Annual amount were examined from 29 rain gages divided among four geographically unique regions 1945/1946 to 2009. Two the displayed significantly declining annual over time series using...

The Kingdom of Saudi Arabia is experiencing an acute shortage freshwater and now looking for new water sources. In 2009, domestic demand was 2,330 million cubic meters (MCM); about 730 MCM wastewater treated 325 the (TWW) reused. remaining typically discharged into Arabian Gulf, Red Sea, sand dunes wadis. These discharges can affect environment groundwater quality. This study investigated TWW reuse potential developed a fuzzy multistage hierarchy framework evaluating in Arabia. research...
