Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Printer-friendly Version Interactive Discussion EGU Abstract A data mining, regression tree algorithm M5 was used to review the understanding of mutual hydrolo...
[1] Vegetation affects the climate by modifying the energy, momentum, and hydrologic balance of the land surface. Soil-vegetation-atmosphere transfer (SVAT) schemes explicitly consider the role of vegetation in affecting water and energy balance by taking into account its physiological properties, in particular, leaf area index (LAI) and stomatal conductance. These two physiological properties ...
Reliable estimation of hydrological soil moisture state is of critical importance in operational hydrology to improve the flood prediction and hydrological cycle description. Although there have been a number of soil moisture products, they cannot be directly used in hydrological modelling. This paper attempts for the first time to build a soil moisture product directly applicable to hydrology ...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
یکی از روشهای معتبر در شبیهسازی فرآیند پیچیده و غیرخطی بارش–رواناب استفاده از مدلهای هیدرولوژیکی است. هدف مقاله حاضر بررسی کارایی سه مدل بارش-رواناب یکپارچه و مفهومی AWBM، Sacramento و SimHyd در شبیهسازی رواناب روزانه در خروجی حوضه آبریز معرف امامه با کاربرد بهینهساز واسنجی خودکار الگوریتم ژنتیک است. مشابه سایر مدلهای هیدرولوژیکی، در هر سه مدل مذکور محدوده تغییر پارامترها زیاد است و با ت...
Hydrological models have been increasing in complexity over the years. These models rely on their calibration to simulate real world conditions as close as possible. Calibration is a tedious and time-consuming process. An auto-calibration algorithm (SCE-UA) developed by Duan et al. [1992], has been successfully used in hydrological modeling area. This is a serial algorithm and as complexity of ...
Hydrological conditions determine the distribution of plant species in wetlands, where conditions such as water depth and hydrological fluctuations are expected to affect the interspecific interactions among emergent wetland species. To test such effects, we conducted a greenhouse experiment with three treatment categories, interspecific interaction (mixed culture or monoculture), water depth (...
Large-scale hydrological models are important decision support tools in water resources management. The largest source of uncertainty in such models is the hydrostratigraphic model. Geometry and configuration of hydrogeological units are often poorly determined from hydrogeological data alone. Due to sparse sampling in space, lithological borehole logs may overlook structures that are important...
