Geological Considerations Before Installing Ground Source Heat Pump Systems

As the GSHP systems have relatively high installation costs, it is important that geological data and knowledge is available so that costs can be minimized. Furthermore, detailed geological information like surface and sub-surface temperature, thermal properties of the soil, water table, flow direction and type of soil etc. is also required for efficient design of the system.

Factors Affecting Trip Generation in Traffic Studies

The trip generation aims at predicting the total number of trips generated and attracted to each zone of the study area. In other words this stage answers the questions to / how many trips" originate at each zone, from the data on household and socioeconomic attributes. Purpose of the trip generation studies is to predict the number of the trips to be made

Biological Nitrification Process in Waste Water Treatment System

Total concentration of organic and ammonia nitrogen in municipal wastewater in the range 25‐ 45 mg/L as nitrogen based on flowrate of 450 L/capita.d (120 gal/capita.d). With limited water supplies, total nitrogen in excess of 200 mg/L as N measured in domestic wastewater. Drinking water maximum MCL for nitrate nitrogen is 45 mg/L as nitrate or 10

Factors Affecting Road / Highway Classification

To identify the classification to which any road belongs, the following factors should be considered: SERVICE FUNCTION:- Most roads provide service to traffic, access to land or both. Following road type provide the service function given as; Freeways and Arterials ==> provide the movement of through traffic. Local roads ==> are used almost exclusively for land

General Considerations and Assumptions in the Soil Stability Analysis

There are three distinct parts to an analysis of the stability of a slope. They are:. If the analysis is for a natural slope, it is essential that the sample be undisturbed. In such important respects as rate of shear application and state of initial consolidation, the condition of testing must represent as closely as possible the most unfavorable conditions ever likely

Factors Affecting Site Selection for Waste Water Treatment Systems

The planning design engineer, when selecting sites for recreational treatment facilities, must ensure that the planned facility will not cause interference or detractions from the natural, scenic, aesthetic, scientific, or historical value of the area. In addition, topographic, geological, hydrogeologic, and atmospheric factors and conditions must be considered

Factors Affecting Type of Canal Lining

When the canal passes through the sandy soil the seepage loss is at maximum and the canal is unstable. So, to make the canal perfectly impervious and reasonably stable, the most impervious types of linings should be recommended such as cement concrete etc. The smoothness of the canal bed and sides increases the velocity of flow which further increases

Factors Affecting Design of a Barrage

Factors affecting the Design of Barrage are as follows: Estimation of Design Flood Hydraulic Units Width of Barrage Afflux Tail Water Rating Curve Crest Levels Discharges through a Barrage (Free Flow Conditions) Discharge through a Barrage (Submerged Flow Conditions) Fane's Curve Gibson's Curve

Factors Affecting Structure Shape and Capacity of Culverts

Ideally, the axis of a culvert should coincide with that of the natural stream bed and the structure should be straight and short. This may require modification of the culvert alignment and grade. Often it is more practical to construct the culvert at right angles to the roadway. However, the

Methods of Improving and Factors Affecting Duty of Water

If the soil of the canal bed is porous and coarse grained, it leads to more seepage loss and consequently low duty. If it consists of alluvial soil, the percolation loss will be less and the soil retains the moisture for longer period and consequently the duty will be high.... When the

Selection of Site for Cross Drainage Works

The factors which affect the selection of suitable type of cross drainage works are: 1. Relative bed levels and water levels of canal and drainage. 2. Size of the canal and drainage. 3. When the bed level of the canal is much above the HFL of the drainage, an aqueduct is the obvious choice. 4. When the bed level of the drain is well above FSL of canal, super passage is provided

Factors Affecting Location and Necessity of Spillways

The height of the dam is always fixed according to the maximum reservoir capacity. The normal pool level indicates the maximum capacity of the reservoir. The water is never stored in the reservoir above this level. The dam may fail by over turning so, for the safety of the dam the spillways are essential. The top of the dam is generally utilized by making road.

Parameters considered in Designing Spillways

The topography, hydrology, hydraulics, geology and economic considerations all have a bearing on these decisions. For a given inflow flood hydro graph, the maximum rise in the reservoir level depends on the discharge characteristics of the spillway crest and its size and can be obtained by flood routing. Trial with different sizes can then help in getting the optimum combination

Effect of Rock Structure and Composition on Weathering

Rock structure includes joints, beding planes, folds, fractures, and faults. Rocks containing these structures will be easily subjected to weathering. There are certain elements which are included in rock composition. Some rocks will weather quickly and some slowly e.g. acidic rocks weather more quickly than basic ones. It includes the meteorological elements effect on rocks

Weathering - Definition and Types of Weathering

It is the process of weakening rock and producing a rock waste or soil cover. Weathering occurs when rocks and minerals comes in contact with the atmosphere, organic life and suicidal water. Essential feature of weathering is that it affects rocks in-situ (in place) and no transportation of material is involved. A part of rainfall always snips into the soil on the covered rocks
