Аннотация: This book deals with use of stochastic integral equations. Various aspects of the rainfall-runoff modeling process are crutinized by use of probabilistic models, such that when combined, a stohastic integral equation results. Uncertainty in single event runoff estimates, as well as return frequency event outcomes are analyzed. Use of example problems demonstrate the application of stochastic integral equations in addition to explaining the underlying concepts. Computer program source code is also provided which can be used to solve both theoretical and real-world problems. The generous supply of chapter problems enables the book to be used as an applied textbook in stochastic integrals.

Аннотация: The quantity and regularity of stream flow and its variations are matters of much importance in hydraulic engineering, and equally so to many of the bisness interests and enterprises of the State of Wisconsin. One of the most important elements in the solution of all of these problems, is the condition of stream flow or runoff

fertilization -- peatland -- runoff -- water chemistry

Аннотация: In peatland forestry, fertilization is often needed to reach a good yield. Phosphorus and potassium are mainly used, but on nutrient poor fens and bogs nitrogen also has to be added. These fertilizers affect the environment and thereby influence the runoff waters.The aim of this investigation were to determine the concentrations of fertilizer compounds in runoff water downstream from the fertilized mires and to calculate the losses of applied fertilizers. Consequences on pH and biota, primarily fish, from increased concentrations of fertlizers in the runoff waters were to be investigated

clear-felling -- groundwater level -- peatland -- runoff -- inundation

Аннотация: High floods in watercourses are of great interest, because of the potential hazards they pose to people and low-lying land near rivers. In many parts of the world, inundations are common and in northwest Europe there are high discharges almost every year, occasionally with serious consequences. In Sweden, such a major flood occurred in 1985, causing a damburst. Land use in the area was mainly forestry, and fairly extensive clear-felling and drainage were believed to have amplified high discharges following heavy rain. This led to investigation of the hydrological consequences of this forestry activities. Drainage was carried out both as new drainage of virgin peatlands, and as drainage of moist and wet mineral soils, i.e. remedial drainage of clear-felled areas. The investigations were made on small catchments and utiliesed the calibration period and control basin technique, using lenear regression ralations. Drainage of clear-felled areas partly led to reduced peak flows. A high grounwater level was an important prerequisite for increased discharges.

phosphorus -- nitrogen -- leaching -- fertilization -- peatlands

Аннотация: The leaching of elements from artificial basins (drained in 1967) in Central Finland was studied. 4 basins were fertilized in 1987 before snowmelt, and 4 basins after snowmelt. 500 kg/ha of a commercial PK-fertilizer and 215 kg/ha of urea were applied. 8 basins were left unfertilized. Extremely high runoff water N-, P-, K-< Ca-, Mg-, Na-, S- and B-concentrations were observed during the snowmelt period. Except for nitrogen, considerable leaching occurred from the basins that were fertilized after snowmelt as well. The distinct decrease in runoff water pH as well as long-term leaching of phosphorus appear to be the most serious environmental effects of the fertilizations.
