Subject syllabus

1. Hydrology as a science - basic concepts, meaning, development.
2. Basic hydrological unit - basin. Basic characteristics of the river basin - river basin area, number of the hydrological order of the river basin (partial plots), aging, river slope, river network density, river basin shape, etc.
3. Work with basic water management map and its key. HEIS information portal.
4. Geographical characteristics of river valleys and river basins - types of river network, slope of stream, natural processes of erosion, transport and accumulation of watercourse.
5. Flow in the stream bed - laminar, turbulent, spiral, influence on erosion and accumulation processes in the stream. Movement of suspended solids and sediments. Quantification of sediments and suspended solids (grain size analysis, grain size curve, boulder measurement, determination of suspended solids). Sediment regime of calm and streams.
6. Water level, characteristics (zero gauge, prism profile) and its changes - water levels and observation devices (gauges, limnigraphs, ultrasonic devices). Methodology of water level measurement. Processing and use of results, quantities required in practice. Information and forecasting of water levels (forecasting, information and warning service).
7. Flow - characteristics, required quantities in practice. Indirect measurement method - profile selection, measuring equipment, measurement methodics for calculation of actual flow rate. Measuring equipment - OTT-type propellers, modern methods - ADCP.
8. Construction of flow rate curve, flow calculation methods and their graphical
expression. Hydrotechnical calculation of flow rates according to the Chézy equation.
9. Long-term average annual flow and its derivation. Extreme flow of their evaluation. Calculation for different probability of exceeding from observation result, calculation in case of lack of observation. Minimum flow rates - Daily flow values, Maximum flow rates - Mineral flow values. Use in practice - delineation of inundation areas for Groundwater.
10. Ice effects. Hydrological regime of rivers. Types of modes.
11. Water runoff - characteristics, types of runoff. Drain calculations, total drainage, drainage height, drainage factor, etc.
12. Hydrological balance of water circulation, calculations. Required quantities: precipitation, evaporation, flow, runoff, their interpretation.
13. Working methods - method of observation and evaluation of hydrological phenomena, frequency and exceedances (symmetric and asymmetric), relations of sets of observed values ​​(hydrological series balancing, harmonic analysis).
14. Extreme phenomena in hydrology. Floods - types of floods according to genesis. Flood control measures in the landscape. Drought (meteorological, hydrological, agricultural). Measures in the landscape in the context of hydrological drought.
