Growth and decline of fishery in Poděbrady and Nymburk Estates from the point of view of historical hydrology
This contribution presents a current occurrence of drought periods and declines of fishponds (including entire fishpond systems), in Poděbrady and Nymburk counties. Such relation is not straightforward, when we consider fishponds as reservoirs of water and energy.
This contribution is a complication of the biggest floods in the Czech Republic that have occurred in the last hundred years and provides descriptions of these individual disasters.
In 1989, Prague units organizational and dislocation structure of the Water Research Institute (WRI) was rather rugged. It consisted of the traditional components of water management research, referred to collectively as section 20 located in Podbaba, and an experimental group dealing with wastewater treatment in Papírenská Street.
Evaporation from free water surface is one of the important factors affecting the total water balance of a catchment. Since direct measurement of evaporation is complicated, evaporation is in practice often calculated using formulas based on common meteorological variables.
The first part the present study contains recommendations for the selection of representative observation period used for the calculation of average flow characteristics. This is the result of calculations based on time series of flows of the Vltava River in Prague with beginning in 1801.
The article deals with the assessment of the hydrological balance in a monthly time step in the territory of the Czech Republic, which was divided into 133 sub-basins for the period 1981–2015.
Possible compensation of negative climate change impacts using the localities for potential accumulation of surface water
The list of localities potentially suitable for accumulation of surface water (LASW) exists in the Czech Republic from the beginning of 20th century.
