COMBINING PROBABILITY OF EMPTINESS AND MEAN FIRST OVERFLOW TIME OF A DAM TO DETERMINE ITS CAPACITY
Stochastic simulation dam process behavior analysis
2014/11/12
Probabilistic considerations have been practiced in determining the capacity of a dam after the
introduction of probability theory of dams by P. A. P. Moran (1954). Various researchers determined
th...
First super-high-resolution model projection that the ancient “Fertile Crescent” will disappear in this century
First super-high-resolution model streamflow Jordan River
2009/4/13
The first full projections of rainfall and streamflow in the “Fertile Crescent” of Middle East are presented in this paper. Up until now, this has not been possible due to the lack of observed data an...
First estimate of the future global population at risk of flooding
devastating flood global population
2009/4/13
Flooding is one of the major risks anticipated to increase in association with anthropogenically induced climate change which is likely to intensify the global water cycle. Currently, 20 to 300 millio...
Response of a first-order stream in Maine to short-term in-stream acidification
stream acidification ion exchange
2009/3/24
An experimental short-term acidification with HCl at a first-order stream in central Maine, USA was used to study processes controlling the changes in stream chemistry and to assess the ability of str...
Critical loads of sulphur and nitrogen for freshwaters in Great Britain and assessment of deposition reduction requirements with the First-order Acidity Balance (FAB) model
critical loads acidification nitrate FAB model
2009/3/24
The critical loads approach is widely used within Europe to assess the impacts of acid deposition on terrestrial and freshwater ecosystems.
Present and potential nitrogen outputs from Norwegian soft water lakes – an assessment made by applying the steady-state First-order Acidity Balance (FAB) model
Lakes hydrochemistry nitrogen nitrate sinks
2009/3/17
The steady-state First-order Acidity Balance (FAB) model for calculating critical loads of sulphur (S) and nitrogen (N) is applied to 609 Norwegian soft-water lakes to assess the future nitrate (NO3&#...
First evidence of a structured and dynamic spatial pattern of rainfall within a small humid tropical catchment
catchment Malaysia monsoon rainfall spatial variability
2009/3/12
In a study of the spatial variability of rainfall across a network of 46 raingauges in a 4 km2 rainforest catchment in the interior of northeastern Borneo, seasonal rainfall totals were correlated wit...
