San Juan River (Calamba)
The San Juan River ( tl, Ilog ng San Juan), also known as Calamba River, is a river system in Calamba, Laguna, Philippines. It is one of 21 major tributaries of Laguna de Bay and is regularly monitored by the Laguna Lake Development Authority (LLDA) through one of its 15 river monitoring stations. Along with the San Cristobal River, it is one of the two major rivers of Calamba that drains into Laguna de Bay. Its watershed area covers Calamba City in Laguna and the municipalities of Santo Tomas, Tanauan, and Malvar in Batangas. Monitoring and conservation In the December 2005 LLDA Water Quality Status Report, the San Juan River was listed as "''worse than Class D''" with a very low percentage of dissolved oxygen saturation. It also indicated that this status had not improved since the river had last been monitored. According to the Department of Environment and Natural Resources's Water Usage & Classification for Fresh Water, Class D freshwater is suitable for agricultu ...

San Cristobal River
The San Cristobal River ( tl, Ilog ng San Cristobal) commonly known as Matang Tubig River is a river system in the cities of Calamba and Cabuyao, Laguna, Philippines. The river is one of 21 major tributaries of Laguna de Bay. Hydrology The main source of the San Cristobal River is Mount Sungay, the highest mountain of Cavite province, where the main stem and its tributaries drain the northern and eastern side of the mountain. Its watershed area covers Calamba and Cabuyao in Laguna, Tagaytay and municipality of Silang in Cavite. The river system of San Cristobal from Mount Sungay is connected to the Matang Tubig located in Casile and Canlubang. Water quality Along with the San Juan River, the two rivers act as natural drainage systems by receiving and conveying Calamba's (and Cabuyao's for San Cristobal) liquid wastes and storm surface runoff to the nearby Laguna de Bay. Both rivers are very polluted as a result, thus, affecting the water quality of the lake as well. Al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of The Philippines
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, an ...

Dissolved Oxygen
Oxygen saturation (symbol SO2) is a relative measure of the concentration of oxygen that is dissolved or carried in a given medium as a proportion of the maximal concentration that can be dissolved in that medium at the given temperature. It can be measured with a dissolved oxygen probe such as an oxygen sensor or an optode in liquid media, usually water. The standard unit of oxygen saturation is percent (%). Oxygen saturation can be measured regionally and noninvasively. Arterial oxygen saturation (SaO2) is commonly measured using pulse oximetry. Tissue saturation at peripheral scale can be measured using NIRS. This technique can be applied on both muscle and brain. In medicine In medicine, oxygen saturation refers to ''oxygenation'', or when oxygen molecules () enter the tissues of the body. In this case blood is oxygenated in the lungs, where oxygen molecules travel from the air into the blood. Oxygen saturation (() sats) measures the percentage of hemoglobin bindin ...

Tributaries
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & Sco ...
