- Understanding the potential impact of floodwater on a site
- is carried out to quantify the flow or volume of water in a river or stream, over land, in soils, in a pond or in a reservoir.
HYDROLOGICAL STUDY
49
what is HYDROLOGICAL STUDY?
A hydrological study refers to a set of measures or infrastructure designed to manage and mitigate the risk of flooding in a particular area. To further understand the potential impacts of floodwater on a site, an assessment is carried out to quantify the flow or volume of water in a river or stream, over lands, in soils, in a pond, and a reservoir. There are various types of hydrological studies to obtain the needed information to manage the vital resource: Analysis of rainfall, delineating channels and waterways, evaluate the capacity of the existing drainage, and recommending flood control system.
50
what is SOIL INVESTIGATION?
Soil Investigation is understanding the soil in a particular area and how they affect hydrology, construction, erosion control, and plant growth. It helps to determine the properties and characteristics of the soil on a site. Determining the properties and characteristics of the soil help’s ensure the safety, stability, and sustainability of the site and its surrounding environment. All information regarding the investigation of soils is crucial for designing stable and reliable foundations for structures such as buildings, bridges, or other infrastructure.
51

SITE SPECIFIC INVESTIGATIONS
53
- conditions may include features unique to a particular region, such as acid soils, limestone sinkholes, perched groundwater tables, peat deposits, or organic soil deposits.
CRITICAL CONDITION
54
- from the geotechnical or engineering viewpoint, soil may be defined as an accumulation of solid particles generated from the physical and chemical weathering of parent rock.
- soil, therefore, contains three phases: solids, water, and air.
SOIL PHASES
55
- these properties can include particle size, shape, and mineralogy, along with structure, texture, color, organic matter content, pH, and others.
- physical properties such as density, moisture content, and specific gravity provide useful information to geotechnical experts and reveal how the soil will behave or perform as a construction material.
PHYSICAL PROPERTIES
56
- first developed to describe soils for agricultural purposes.
- textural designations are based on three major particle size groups: sand, stilt, and clay
USDA Textural Classification
System
57
- distinguishes soils based on their engineering performance as a construction material, and it considers texture, gradation, plasticity, and organic matter content.
Unified Soil Classification System - USCS (ASTM D-2487)
58
- classification systems generally describe soil particles as cobble, gravel, sand, stilt, and clay, based on size.
GRAIN SIZE
59
- is defined as what a soil is able to support per unit area.
BEARING CAPACITY
60
- determines the stability of a soil and its ability to resist failure under loading.
SHEAR STRENGTH
