Prologue to Hydrology ? Advancement of Hydrology ? Hydrologic Cycle ? Australian Hydrology INTRODUCTION 6 DEFINITION OF HYDROLOGY Greek word: Hydor = water ology = investigation of Hydraulics originates from Greek word hydraulikos which thus originates from hydor (Greek for water) and aulos (which means pipe). Meaning OF HYDROLOGY UNESCO (1979)1 characterizes hydrology as â€Å"the physical science which treats the waters of the Earth, their Occurrence, Circulation and Distribution, their Chemical and Physical Properties, and their Reaction with the Environment†. UNESCO, (1979), Impact of urbanization and industrialisation on water assets arranging and the executives, Studies and Reports in Hydrology, UNESCO, UNESCO, Paris. 7 Water is basic for support of life. Early civilisations were focused on streams ? ? foundation of settlements close to waterways similar to searching for indications of water on Mars Management of water is multi-disciplinary; numerous callings are included. WATER Variety of issues experienced incorporate ? Flood relief ? Clean sewer frameworks ? Land waste ? Water Supply ? Duct and extension plan ? Natural Flows ? Disintegration ? Mine tailings ? Dry spell ? Adjustment to environmental change ? Water system frameworks ? Hydro-electric and force age ? Stormwater frameworks 8 RURAL FLOODING URBAN FLOODS 9 STORMWATER STRUCTURES STORMWATER DRAINS 10 WATER SUPPLY HYDRO-ELECTRIC POWER 11 IRRIGATION SCHEMES DROUGHT 12 DEVELOPMENT OF HYDROLOGY Ancient civilisations were coordinated with their waterway valleys. Models are ? ? ? ? ? Egyptian Civilisations and the Nile Valley Mesopotamian Civilisations and the TigrisEuphrates Indian Civilisations and the Indus Valley Ancient China and the Yellow River Andean Civilisations and Coastal Peru DEVELOPMENT OF HYDROLOGY Huge numbers of structures from early civilisations are still in activity. Huge scope water system and seepage works were related with these civilisations. Most punctual recorded dam is about 2900BC (the Sadd Al-Kafara at Wadi Al-Garawi, 25km south of Cairo) Used for both flood assurance and water system. Likewise site of soonest known dam disappointment. 13 DEVELOPMENT OF HYDROLOGY Oldest enduring dam on the planet is the Grand Anicut Dam on the Kaveri River in Southern India. This structue goes back to second Century AD. Advancement OF HYDROLOGY Water flexibly to Ancient Rome has been assessed as being approx 500L/c/d. Flow water flexibly prerequisites are ? ? ? Australian urban communities, plan †approx. 430L/c/d Australian urban areas, genuine †approx. 230L/c/d US urban communities, plan †approx 600L/c/d Drainage structures, (for example, the Cloaca Maxima) from Ancient Rome are as yet being utilized today. 14 ANCIENT ROMANS Cloaca maxima Bath, UK AQUEDUCTS Pont du Gard, France c19 BC Hampi, India first century AD 15 DEVELOPMENT OF HYDROLOGY Flood insurance has been rehearsed for a huge number of years along the Yellow and Yangtze Rivers. It stays an issue of worry in these regions to the present day. Advancement OF HYDROLOGY Water has been of enthusiasm for a long time. Antiquated Greek and Roman logicians conjectured on a hydrologic cycle †Homer, Plato, Aristotle, Lucretius, Seneca, Pliny. This cycle was created from their perceptions of water in their condition. Utilization of perceptions stays a principal segment of ebb and flow hydrologic applications and research. 16 DEVELOPMENT OF HYDROLOGY Chinese recorded perceptions of downpour ? ? ? A yang prophet bones as ahead of schedule as 1200BC; Used downpour measures around 1000BC; and Established precise records about 200BC. Indian records go back to 400BC. Improvement OF HYDROLOGY Scientific advancement of hydrology happened uring the Renaissance time frame. Models are ? ? ? Leonardo da Vinci †speed conveyances in streams. Bernard Palissy †springs started from precipitation. Pierre Perrault †overflow is a small amount of precipitation. 17 DEVELOPMENT OF HYDROLOGY Other commitments during this period were made by ? ? ? ? ? Galileo Newton Bernoulli Euler Lagrange DEVELOPMENT OF H YDROLOGY Significant logical advancement happened in the nineteenth Century when ? ? ? ? ? Dalton proposed the standard of vanishing. Hagen-Poiseuille portrayed fine stream. Mulvaney built up the Rational technique. Darcy depicted scientifically permeable media low. Rippl created strategies for deciding stockpiling prerequisites. 18 DEVELOPMENT OF HYDROLOGY twentieth Century saw quick advancement of quantitative hydrology. Greatest impact during this period was the advancement of the computerized PC and the improvement of catchment displaying frameworks. Restriction currently is information accessibility instead of computation limit. HYDROLOGIC CYCLE 19 HYDROLOGICAL CYCLE One of the principal patterns of nature. Reason for the study of hydrology. Significant focuses ? ? ? ? Cycle has no beginning and no closure. Cycle is constant. Stream of water in the cycle isn't consistent. Water moves sporadically through the cycle. HYDROLOGICAL CYCLE 20 HYDROLOGICAL CYCLE HYDROLOGICAL CYCLE 21 HYDROLOGICAL CYCLE HYDROLOGICAL CYCLE General segments of the cycle are ? Climatic Water ? Surface Water ? Ground Water In examination of water asset issues, these segments are treated with a frameworks approach. You read Water power and Hydrology Lec in classification Papers 22 SYSTEMS CONCEPT A frameworks idea is applied while considering the hydrological cycle or some segment thereof. This is predictable with the reductionist idea utilized in many designing issues. Frameworks CONCEPT The reductionist way of thinking depends on lessening the framework to various littler omponents. The reaction of the framework at that point is resolved from summation of the reactions of the individual parts. 23 SYSTEMS CONCEPT WATER BALANCE 24 WATER BALANCE Amount of water doesn't change. Where it might be found changes. Water possibly found in the oceans and seas, in the air, by all accounts, beneath the surface, and in natural frameworks.

Just approx 2. 5% of the water is new water †water in the seas and some lake water and ground water is saline.

This is an utilization of the idea of progression. All in all, utilization of congruity gives in volume terms Inflow †Outflow = Change in Storage (? S) And in motion terms Qi †Qo = ?

Inflow from streams or groundwater (I) 27 WATER BALANCE Components of surge for a water body, for example, a lake or repository are ? Evapo-transpiration (ET); ? Surges †Extractions, Downstream streams, (O); and ? Drainage (G) WATER BALANCE Hence the water balance for a water body is P + I †O †ET †G = ? S 28 WATER FLOWS While the volume of water in a source is significant, the transition of water through a segment is significant too. A sign of the motion can be gotten from the chart of the hydrological cycle. WATER FLOWS The Global Annual Water Balance is appeared on in units comparative with the yearly volume
