This thesis offers with the assessment of floor and groundwater caliber adjustments within the classes of water shortage in river catchment parts. The paintings could be divided into six components. present equipment of drought evaluation are mentioned within the first half, by means of the short description of the software program package deal HydroOffice, designed by means of the writer. The software program is devoted to research of hydrological information (separation of baseflow, parameters of hydrological drought estimation, recession curves research, time sequence analysis). The services of the software program are at the moment utilized by scientist from greater than 30 international locations all over the world. The 3rd part is dedicated to a finished neighborhood overview of hydrological drought on Slovak rivers, via overview of the prevalence, direction and personality of drought in precipitation, discharges, base stream, groundwater head and spring yields within the pilot sector of the Nitra River basin. The 5th half is concentrated at the evaluation of adjustments in floor and groundwater caliber through the drought sessions in the pilot sector. ultimately, the consequences are summarized and interpreted, and rounded off with an outlook to destiny research.

Groundwater Hydrology of Springs: Engineering, Theory, Management and Sustainability
Groundwater Hydrology of Water source sequence Water is a vital environmental source and person who should be competently controlled. because the international locations extra emphasis on sustainable water offers, the call for for services in hydrology and water assets maintains to extend. This sequence is meant for pro engineers, who search an organization beginning in hydrology and a capability to use this information to unravel difficulties in water source administration.

This pocket box advisor explains dry, liquid, and gasoline chemical feed platforms, calibrations, and dealing with and garage requisites for numerous varieties of chemical substances utilized in water therapy. convenient feed calculators for fuel, liquid, and dry chemical substances are integrated
Water Security: Principles, Perspectives and Practices
The aim of this publication is to present an outline of the newest study, coverage, practitioner, educational and foreign pondering on water security—an factor that, like water governance many years in the past, has built a lot coverage information and momentum with a variety of stakeholders. As an idea it's open to a number of interpretations, and the authors the following set out a few of the ways to the subject from assorted views.
Understanding Mathematical and Statistical Techniques in Hydrology: An Examples-based Approach
Decide up any hydrology textbook and it'll now not be lengthy sooner than you come across pages directory sequences of equations representing complicated mathematical suggestions. scholars and practitioners of hydrology won't locate this very useful, as their goal, typically, is to check and comprehend hydrology, and never to discover themselves faced with fabric that even scholars of arithmetic may locate hard.

Both authors solve an analysis of recession curves and their mathematical simulation and modeling. From the Slovak authors, the recession curves were dealt mainly by Kullman and Petráš (1977, 1979) who have emphasized the reflection of filtration coefficient on the practically all lithological, tectonic and spatial characteristics of the rock massif, as well as properties of the hydrogeological structures. They also pointed to the possibility of using the recession curves analysis for the quantitative assessment of changes in water reserves and its transfer between seasons.
Monitoring with daily or monthly step (applied in assessing the changes in water quality, depending on climatic factors). • Monitoring for assessment of seasonal and longer biological cycles. • Monitoring with an annual time step (used to assess long-term human impacts on water quality). 3 Strategies for Water Quality Assessment Water quality monitoring is a complex issue, that uses a variety of data collection methods, statistical processing, modeling and results interpretation. The most significantly the need for the monitoring of the water quality increased since 1950.
For the frequency analysis the following distribution models (Fleig 2004) can be used in the program: • • • • • • • Poisson distribution Pascal distribution Gamma/Pearson type 3 distribution Weibull distribution Log-normal distribution Johnson distribution Double exponential/Gumbel or generalized Patero distribution Drought Characteristics in Groundwater The groundwater hydrological drought in hydrological system is assessed very rarely. In the past, many of authors have considered that the sign of drought in the groundwater was caused by the excessive pumping of the water rather than a result of natural climate variability (Day and Roda 1978).
