ABSTRACT In this research, two scenarios of drought forecast were studied. the first scenario, time series monthly streamflow converted into Standardized Hydrological Drought Index ( SHDI ), a similar index to well‐known Precipitation SPI ). Multi‐layer feed‐forward artificial neural network FFANN ) was trained with hydrological Karoon River in southwestern Iran. second discharge forecasted directly and then . Principal component analysis PCA forward selection FS techniques applied remove...
ABSTRACT In an era of unprecedented environmental shifts, assessing climate change's repercussions is paramount. This study investigates the impact change on floods in Kashkan watershed, western Iran, for near future (2030–2059) and far (2060–2089). A HEC–HMS model was developed calibrated from January 1997 to December 2012 validated 2013 August 2019. To enhance simulation precision, we employed long short-term memory (LSTM), reducing annual average error peak flow 23.62 9.49%. We selected...
ABSTRACT Accurate hydrological modeling is essential for understanding and managing water resources. This study conducts a comparative analysis of strategies in date-scarce region. examines lumped (IHACRES), semi-distributed (HEC-HMS), hybrid-lumped/long short-term memory (LSTM) models, aiming to assess their performance accuracy data-scarce It investigates whether lump models can accurately simulate flow evaluates the impact combining with machine learning enhance accuracy, compared models....
The purpose of this study is to survey the impact climate change on runoff Gharehsoo River in northwest Iran. In research outputs monthly precipitation and temperature data PRECIS model, which a regional model with 50 × km resolution basis B2 scenario, have been utilized for base (1961-1990) future (2071-2100) periods. output results show that average watershed increased up 2°C - 5°C. addition, more than January, February, March, September December. observed 1996-2002 used calibration HSPF...
The crucial challenge in arid/developed endorheic basins is to balance agricultural water demands with ecosystem health. This study addresses this dilemma by developing a semi-distributed socio-hydrological model for the using monthly coupled annual Community Sensitivity (CS)/response models. central research question focuses on whether degradation of lakes Tashk-Bakhtegan basin, our selected case study, can shift community's attitude towards allocating resources environmental rather than...
Abstract Water balance models are known as major tools for simulation of basin‐wide water cycle components. Considering the complexity runoff generation processes in karstic basins, it is crucial to bring model closer physical reality springs and their contribution formation. One challenges basin‐scale modelling basins that basin response precipitation highly influenced by soil saturation condition its seasonal variability. way address this challenge include a dynamic structure model. In...
Abstract In an era marked by unprecedented environmental shifts, comprehensively assessing the repercussions of climate change has become a paramount concern. This study investigates impact on floods in Kashkan watershed, located western Iran, for near future (2030–2059) and far (2060–2089). First, HEC-HMS model was developed area, with calibration period from January 1997 to December 2012 validation 2013 August 2019. Subsequently, enhance precision our simulation, we employed long...
Abstract Clay capsule is one of the porous pipes in sub irrigation system that can release water near root zone. This paper has attempted to improve physical and hydraulic properties clay capsules based on organic matter percent changes raw materials. Raw material used for making obtained from calcareous soil Nasr Abad village Gorgan, Iran. The ratio rice bran as improving was 1:2, 1:5, 1: 10, 1:15 1:20 (kg kg air-dried soil). produced were named G2, G5, G10, G15 G20 respectively. discharge...
