River Discharges Forecasting In Northern Iraq Using Different ANN Techniques
Springer Science and Business Media LLC - Tập 28 - Trang 801-814 - 2014
The Upper and Lower Zab Rivers are two of main and most important tributaries of Tigris River in Northern Iraq region. They supply Tigris River with more than 40 % of its yield. The forecasting of flows for these rivers is very important in operation of the existing Dokan Dam on the Lower Zab River and the proposed Bakhma Dam on the Upper Zab River for flood mitigation and also in drought periods....... hiện toàn bộ
Development of a Combined Index to Evaluate Sustainability of Water Resources Systems

Changing Pattern of Droughts during Cropping Seasons of Bangladesh
Springer Science and Business Media LLC - Tập 32 - Trang 1555-1568 - 2018
There has been a growing concern on temporal variations on drought characteristics due to climate change. This study compares meteorological drought characteristics for two different periods to quantify the temporal changes in seasonal droughts of 18 weather stations of the country. Fifty-five years rainfall and temperature data are divided into two different thirty-year periods, 1961–1990 and 198...... hiện toàn bộ
Implementation of Strategies for the Management of Dams with Sedimented Reservoirs
Springer Science and Business Media LLC - Tập 35 - Trang 4399-4413 - 2021
Dams accumulate sediment by interrupting the continuity of rivers, resulting in a loss of reservoir water storage capacity and decreased productive life. These issues raise a growing concern about the decreasing benefits of projects. This paper contributes to the implementation of sediment transit strategies and operating rules of reservoirs to reduce overflows and recover the technical–economic v...... hiện toàn bộ
Reservoir Inflow Prediction: A Comparison between Semi Distributed Numerical and Artificial Neural Network Modelling
Springer Science and Business Media LLC - Tập 37 Số 15 - Trang 6127-6143 - 2023
Reservoir inflow is a major component of the reservoir operations management system. It becomes highly essential to predict the accurate reservoir inflow. The lumped models and semi-distributed or fully distributed model implemented to solve a range of specific problems in the prediction of reservoir inflow. The findings in this paper compare a conceptual semi distributed Hydrologic Engineering Ce...... hiện toàn bộ
Estimation of Runoff Under Changed Climatic Scenario of a Meso Scale River by Neural Network Based Gridded Model Approach
Springer Science and Business Media LLC - Tập 37 - Trang 2891-2907 - 2022
Climate change is linked with change in precipitation, evapotranspiration, and other climatological parameters, and therefore the runoff of a river basin will be affected. The Gomati River basin is the largest in Tripura. The increased settlement in the Gomati River basin and climate change may threaten the natural flow patterns that enable its diversity. This study assesses the impact of climate ...... hiện toàn bộ
Evaluation of three unit hydrograph models to predict the surface runoff from a Canadian watershed
Springer Science and Business Media LLC - Tập 21 - Trang 1127-1143 - 2006
The predictability of unit hydrograph (UH) models that are based on the concepts of land morphology and isochrones to generate direct runoff hydrograph (DRH) were evaluated in this paper. The intention of this study was to evaluate the models for accurate runoff prediction from ungauged watershed using the ArcGIS® tool. Three models such as exponential distributed geomorphologic instantaneous unit...... hiện toàn bộ
Parameters Optimization using Fuzzy Rule Based Multi-Objective Genetic Algorithm for an Event Based Rainfall-Runoff Model
Springer Science and Business Media LLC - Tập 32 - Trang 1501-1516 - 2018
The calibration of an event based rainfall-runoff model for steam flow forecasting is challenging because, it is difficult to measure the parameters physically on the field for each rainfall event. In the present study, Fuzzy rule based Multi-objective Genetic Algorithm (MGA) is developed to optimize the infiltration and roughness parameters of an event based rainfall-runoff model.

Integrated Assessment of no-Regret Climate Change Adaptation Options for Reservoir Catchment and Command Areas
Springer Science and Business Media LLC - Tập 30 - Trang 1001-1018 - 2015
The need for credible, salient and legitimate climate change adaptation options in the water sector, which target location specific adaptation requirements, is well recognized. In developing countries, the low-hanging fruit; no-regret options, should be identified with stakeholders and assessed against future changes in water availability and demand, for comparing effectiveness and robustness.
