| 00:00 | OK. OK. I can't seem get my screen to uh show |
|
| 00:32 | This is here. Thank you. . Uh Once again, with the |
|
| 00:47 | of Utah, we're able to get on track. Uh We talked about |
|
| 00:54 | a tide dominated, I'm sorry, wave dominated delta, basically fils and |
|
| 01:00 | be transformed particularly during a high But in any case, when, |
|
| 01:06 | the sea level is constant and there's lot of fluvial sediment coming in, |
|
| 01:14 | wave dominated estuary fails and becomes a dominated delta. What about the transition |
|
| 01:20 | a tide dominated delta? Because that's we're looking for. And this will |
|
| 01:25 | an example of it again. Uh on the right that we talked about |
|
| 01:31 | the wave dominated system. But on left, uh we find that at |
|
| 01:38 | point you're beginning to have a um sediment depositing here than the tides can |
|
| 01:51 | . And so it becomes a tide delta uh with these linear sandwiches. |
|
| 02:00 | we're gonna talk about those separately. talk about deltas, but just recognize |
|
| 02:06 | uh this is the transition that we're working towards. OK. So here |
|
| 02:13 | the estuary here is the delta and what's happened is we have uh build |
|
| 02:24 | and the tidal flats have migrated the sand bars have migrated out. |
|
| 02:37 | so we're, we're looking at the migration by tidal flat pro gradation and |
|
| 02:51 | of the channels and the bars uh form a delta. So that would |
|
| 02:56 | an example of, of a prorating with the Squam up in Alaska. |
|
| 03:05 | And when we look at these high deltas, one of the things they |
|
| 03:11 | seem to have in common is this and this transition along the rivers, |
|
| 03:20 | is to the from that river tide zone. And if you draw a |
|
| 03:30 | section through here, you would actually that in this portion here, the |
|
| 03:38 | is moving down. And in this here is beginning to accumulate and this |
|
| 03:45 | where the river is gonna start my via a tide dominated delta. |
|
| 03:55 | And that's actually where we're gonna stop what I want to do at this |
|
| 03:59 | and we will take a break uh break um is to look at these |
|
| 04:11 | delta systems and the last of the will basically be that transition with th |
|
| 04:20 | delta. So uh let's take a minute break. Uh Let's see if |
|
| 04:25 | can figure out how to get out this. |
