Reconstructed monthly river flows for Irish catchments 1766-2016. [PDF]

Geosci Data J, 2021
Long‐term river flow records are fundamental for understanding the risk posed by drought and high flow events. Whilst in many locations long‐term flow records are lacking, precipitation data rescue efforts have made extended climatic data readily available and when employed in tandem with hydrological models such data can be used to generate historic ...

The Added Value of Different Data Types for Calibrating and Testing a Hydrologic Model in a Small Catchment. [PDF]

Water Resour Res, 2020
Abstract This study investigated the added value of different data for calibrating a runoff model for small basins. The analysis was performed in the 66 ha Hydrological Open Air Laboratory, in Austria. An Hydrologiska Byråns Vattenbalansavdelning (HBV) type, spatially lumped hydrologic model was parameterized following two approaches.

A model of correction indexes determination for Virginia type tobacco on the basis of field measured ETP [PDF]

Journal of Agricultural Sciences (Belgrade), 2009
Numerous methods of calculating ET0 and ETP offer a great practical possibility for their application, but in order to improve their efficiency it is necessary to check them in particular regions.

Estimating Daily Rice Crop Evapotranspiration in Limited Climatic Data and Utilizing the Soft Computing Algorithms MLP, RBF, GRNN, and GMDH

Complexity, Volume 2022, Issue 1, 2022., 2022
Evapotranspiration represents the water requirement of plants during their growing season, and its accurate measurement at the farm is essential for agricultural water planners and managers. Field measurements of evapotranspiration have always been associated with many difficulties that have led researchers to seek a way to remotely measure this ...

Spatial‐Temporal Interpolation of Reference Evapotranspiration for Pakistan

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
The unequal water distribution in the universe has resulted in more than 2 billion people living in water‐stressed areas. Globally, withdrawals of water resources are still below the critical level. Pakistan is also affected by this serious problem.

Effect of high population density of eastern black rhinoceros, a mega‐browser, on the quality of its diet

African Journal of Ecology, Volume 59, Issue 4, Page 826-841, December 2021., 2021
Abstract High density of herbivore populations can lead to intense foraging competition and depletion of food consequently lowering diet quality and population performance. We tested for the effects of the density of eastern black rhinoceros (Diceros bicornis michaeli) in nine in situ populations of 0.01–0.7 individuals per km2 density range on the ...

Water availability trends across water management zones in Uganda

Atmospheric Science Letters, Volume 22, Issue 10, October 2021., 2021
Study area with locations of datasets. Abstract This study assessed trends in gridded (0.25° × 0.25°) Climate Forecast System Reanalysis (CFSR) precipitation, potential evapotranspiration (PET), and precipitation minus PET (PMP) across the four water management zones (WMZs) in Uganda including Kyoga, Victoria, Albert, and Upper Nile.

Relationships of reproductive performance indicators in black rhinoceros (Diceros bicornis michaeli) with plant available moisture, plant available nutrients and woody cover

African Journal of Ecology, Volume 59, Issue 1, Page 2-16, March 2021., 2021
Abstract Plant available moisture and plant available nutrients in soils influence forage quality and availability and subsequently affect reproductive performance in herbivores. However, the relationship of soil moisture, soil nutrients and woody forage with reproductive performance indicators is not well understood in mega‐browsers yet these three ...
