JNTUH B.Tech 3rd year (3-2) Design of Soil and Water Conservation Structures gives you detail information of Design of Soil and Water Conservation Structures R13 syllabus It will be help full to understand you complete curriculum of the year.
Objective
To enable the students to design and execute the structures for controlling soil erosion, water erosion and irrigation in fields and prepare. cost estimates for the structures.
Unit-I
Introduction, Classification of structures, land treatment structures, gull control structures, functions of soil erosion control structures. Flow in open channels -types of flow, state of flow, regimes of flow, energy and moment.). principles, specific energy and specific force – critical depth concept-stagy discharge relationship-subsequent depths. Hydraulic jump and its application type of hydraulic jump, energy dissipation due to jump, jump efficiency, relative loss of energy – Fronde number and its significance in the design of hydraulic structures.
Unit-II
Runoff measuring structures-Parrish flume, H-Flume and weirs. recorders. Straight drop spill way-general description, ‘functional use, advantages and disadvantages. structural parts and functions, components of spillway. Three design phases – hydro logic and hydraulic design, free board and wave free board, aeration of wires concept of free sub sub merged flow. Structural design of a drop slip ways -loads on head wall, variables affecting equivalent fluid pressure. Determination of saturation line for different flow conditions, seepage under the structure, equivalent fluid pressure of triangular load diagram for various flow conditions. Creep line theory, uplift pressure estimation, safety against sliding, overturning, crushing and tension. Chute spillway- general description and its components, hydraulic design energy dissipates – uplift pressure diagram – analysis of various forces etc Design criteria of a SAF stilling basic and its limitations. Drop inlet spillway. General description, types of possible flow conditions, pipe flow: orifice floor
functional use, design criteria.
Unit-III
Design of diversions, small earth embankments – their types and design principles, farm ponds and reservoirs. Estimation of volume of earthwork o) farm ponds by various methods. Irrigation Engineering structures – Various types and their purposes. Differences between soil conservation and irrigation: structures. Canal Falls – types of canal falls with line diagrams (elevations) Design of trapezoidal notch fall. Design of siphon well drop type of canal falls. Cross drainage works – Locations needing cross drainage works aqueduct – super passage – inverted siphon aqueduct – inlets and outlets – different types of cross drainage works with line diagrams. Design principles of various cross drainage works – Design of an aqueduct.
